Hey - just as another fact:
EPA "does not test every car they rate."
About 15% of the time they actually TEST the car THEMSELVES. The other 85% of the time, they rely on test results given to them by the carmakers.

There was a debate on Edmunds Forums for the last couple of years about whether or not the EPA actually DID the tests on the Prius II. Apparently, the EPA will not divulge that info, so no one REALLY knows.
If the tests came directly from Toyota, then who knows what happened in the testing? Only the people who were there.
